2 nameservers

Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns-c.eurodns.eu, ns-d.eurodns.biz.

#6
✓ Parent and zone agree #7

The parent delegation and the zone's NS records list the same nameservers.
✓ No glue needed #8

All nameservers are outside the zone, so no glue records are needed.
✓ All names resolve #9

Every nameserver name has an address and is not an alias.
✓ Nameservers in different networks #10

The nameservers are spread over 2 IPv4 /24s and 2 IPv6 /48s.
i

All nameservers in one AS

All nameserver addresses are announced by one network operator (AS1921 (RCODEZERO-ANYCAST-SEC1-TLD - ipcom GmbH, AT): 4 addresses). An outage or attack on that network affects all nameservers; large anycast providers mitigate this, but a secondary DNS provider adds independence.

#11
✓ Nameserver names under 2 TLDs #12

Nameserver names use the TLDs .biz, .eu.
✓ All reachable over IPv6 #13

Every nameserver has an IPv6 address.
